Under the passenger side dash/glovebox you will see a wiring harness/connector. It can be hard to see unless you lay on your back on the passenger floor. you will need a socket-and a flashlight/light of some kind. An extension for your socket wrench MAY help you get the right bolt out. If you are having trouble getting the left bolt out you may need to remove the front bolt from the plenum (the thing the air comes from when set to floor/feet). There is a pain in the butt bolt behind the plenum that you may need to loosen to get enough room to move the plenum out of the way. Carefully push the plenum to the front of the truck being careful to not break it! You just need enough room to get the resistor bolt out.
Once you fight with the wiring harness and get it disconnected READ THE RESISTOR INSTRUCTIONS! The new ones have extra tabs that MUST be cut off, if this is the case there will be an instruction sheet with the new resistor. I used a good pair of kitchen scissors.
Before installing the new one inspect the old one. If there is a burnt looking pin (usually #2-second pin from left-there should be numbers on both resistors) you will need to get a new wiring harness, unfortunately I can only find one at the dealer or a salvage/junk yard.
If everything looks good or you have now replaced the harness bolt in the new resistor then carefully pull the plenum back into place. It needs to fit correctly to work. There is a bit of flimsy foam that needs to be in the right place so it won't block airflow. If you accidentally ripped this off you can do 1 of 2 things.
1) use camper tape on the piece the plenum goes over. in other words the piece that is attached to the truck not the removable plenum. It will have to be thin camper tape
2) Duct Tape the outside of the plenum. there are other tapes you can use but you need to be able to remove the tape for future repairs.
It is under the hood in the passenger side firewall.
Under the dash, far passenger side.
replace the blower fan resistor and you`ll be okay
Diagram for location of blower motor resistor can be found herehttp://autorepair.about.com/library/images/bl441a-lib.htm
Your truck has both. the resistor is between the switch & blower.thje resistor controls the blower speed
A 1998 Dakota does not have a ballast resistor.
most common problem is the blower resistor In the firewall on the passenger side of the truck is the blower motor speed resister coils, they burn out alot. I could not find one for my Dakota so I got one from a dodge caravan and I changed the wirring, that is the most likely problem
Under the dash below glove box. You will see the blower motor and it's to the left of it. You will see a wire harness going to it.
check the blower motor resistor pack. should be firewall side of heater rectangular connector with 4 or 5 wires.
I have changed resistor a d blower motor still not working, maybe i missed a fuse or could the control switch not work?
For the 1989 Dodge Ram, the heater blower motor resistor can be found on the passenger's side, on the bottom of the heater box. It is beside the blower motor.
The resistor just helps in the different speeds, and isn't used at all during hi speed, Access it under the passenger side of the dash.The resistor, and the blower motor are both easy to get to
The front blower resistor on a 98 Dodge Caravan is replaced by removing the cover and disconnecting the wiring harness. The resistor can then be pulled and a new one put in its place.
For a 1999 Dodge Dakota the Blower resistor is located in the firewall under the Cowl panel (Plastic panel under wipers). The wiper arms must be removed to remove the cowl panel. The resistor is located on the passengers side inside an access hole. My blower only works on High. I just removed my resistor and found that the connector was not plugged into the resistor. I finally found the plug under the dash. Does anyone have any idea on how to plug the connector back into the resistor without removing the complete instrument panel??
Under the hood on the passenger side you will see a small box on the firewall with a plug-in...its held in with two screws..remove the plug-in, the screws and pull out the resistor. replacement is the reverse.
Inside the cab. Passenger side. Inspect the heater ducts Look for five wires going to the resistor. Should be two screws holding it in.
The blower motor resistor pack is defective. Replace it.
Not always, but 99% of the time this is a sign that the Blower Motor Resistor Pack is defective. Replace it.
Blower motor is under the dash on the passenger side.
The Blower resistor should be tested which is located near the blower motor, the resistor is probably faulty.
I belive it is located down under the dash on the passenger side. the older dakotas where mounted on the passenger side of the fire wall. a blower motor resister is usually located close to the actual blower motor.
Could be a bad blower motor, or, look to the blower motor resistor mounted on the engine firewall on the passenger side near the top of the firewall inside the engine compartment. It will have five wires going to it. It is likely either burnt out, or the wires have shorted at or near the resistor.
I have been working on an issue with my 2002 Dodge Ram. The blower motor and resistor are both located on passenger side under the dash. Easily accessible in cab.
It is under the hood, far passenger side of firewall. It is near the top, just above the wiring harness.
Somewhere in the path of the air that the rear blower motor blows
